First on, last off, our exceptional, moisture-wicking Sender Boxers provide an unsurpassed foundation for any active day. Made with a laser focus on materials, fit and support, the Sender Boxers have a moisture-wicking micromesh fabric of recycled nylon and spandex that feels airy and light, stretches when you move, wicks moisture and dries in a flash. We added an anti-roll, comfort waistband that stays put without pinching, binding or chafing, even when you’re running after the day’s last train. The bulk-free fit has ergonomic shaping and patterning to keep these boxers from riding up or bunching. Flatlock, chafe-free seaming throughout means all-day comfort under pack straps or harness. With a fully functioning fly. Sender Boxers are also Fair Trade Certified™ sewn, which means the people who made them earned a premium for their labor.

Fair Trade Certified™

We pay a premium for every Fair Trade Certified item that carries our label. That extra money goes directly to the workers at the factory, and they decide how to spend it. The program also promotes worker health and safety and social and environmental compliance, and encourages dialog between workers and management.

bluesign® Approved Fabric

Patagonia has worked with bluesign technologies since 2000 to evaluate and reduce resource consumption in our materials supply chain, and to assist us with managing the chemicals, dyes and finishes used in the process. bluesign technologies, based in Switzerland, works at each step in the textile supply chain to approve chemicals, processes, materials, and products that are safe for the environment, safe for workers, and safe for the end customers.

In 2007, Patagonia became the first brand to officially join the network of bluesign® system partners.

Any fabric you see that’s bluesign® approved offers the highest level of consumer safety by employing methods and materials in their manufacture that conserve resources and minimize impacts on people and the environment.
